Green onions occupy a very important position in vegetable cultivation. Whether it is a family or a large planter, green onions are grown every year. This is because every household in the cooking industry uses it, so the market demand for green onions is very large, and there are many natural plants. For the cultivation of green onions, naturally the higher the yield, the better, then how to grow green onions will be high-yield? These points must be understood.
The first point: green onion planting time
1. Autumn planting time: The first year of autumn, planting in early September, with the seedlings overwintering, and planting in the early summer of May of the second year, then it can be harvested before winter, and can be stored in winter or in the open field.
The seedlings are wintering, the second year of summer is planted in mid-May, harvested before winter, and the winter is hidden or exposed. In the third year, the flowers are drawn in the spring and the seeds are harvested in the same season. The seedlings at the time of planting can be listed in the first half of May to the end of June; or the flat stalks can be used to reduce the plant spacing and planting the stalks as the scallions, or as the early spring stalks.
2, spring planting time: generally in the early spring for sowing, and after the soil is thawed, it can be used as a supply of shallots before the onset of summer. After the onion is planted, the harvest can be used as the dried onion or ditch, which can be used as the wintering horn. Onions or seed plants.
3, summer planting time: more in the late July to early August sowing, it is also known as the onion. When the winter is over, the plants are larger. It is easy to complete the vernalization process. It sprouts early in the spring and can be quickly convulsed and flowered, so it is generally listed after the squash.
The second point: what varieties of green onions are good
As a green onion cultivated in the four seasons, it is a variety that has the characteristics of cold resistance, drought resistance, heat resistance, strong adaptability, long white onion, and no separation. For example, Chinese green onions, Zhangqiu green onions (high white) or local farmer varieties shallot. The onion varieties should not be cultivated in the four seasons.
The third point: how can we make green onions high yield?
1, early preparation, early transplanting, rational close planting is the key
Years of production experience has shown that the early transplanting of green onions has a significant increase in the yield of green onions. In addition, reasonable close planting is an important measure for the high quality and high yield of green onions. The general plant spacing is 4-6 cm, and the row spacing is 25-30 cm.
2, cultivating alfalfa should be timely, in order to prevent rotten roots
The cultivating can promote the growth of the roots of the scallions and increase the permeability of the soil. When the scallions are planted, the seasons are high in temperature and rainy, and there are many weeds. Therefore, weeding must be carried out in time to prevent grass shortage; July and August are concentrated in the northern regions. During the rainfall period, it is easy to cause the roots, yellow leaves and dry tips of the green onions. In addition to doing well the anti-cold water, it is necessary to break the table and break the table so that the roots of the green onions can carry out various normal activities.
3, the bottom fertilizer should be appropriate, high-yield quality and guaranteed
The main or green onion needs to be determined according to the fertility of the planting area and the growth of the green onion. Generally, the first fertilization is carried out after the beginning of autumn. According to the normal fertilization situation, about 2,000 kg of soil fertilizer is required per mu, or Use two hundred kilograms of cake fertilizer, plus twenty kilograms of urea.
After waiting for the second top dressing after the heat, this fertilization requires about 15 kg of urea. The last thing is to look at the growth of green onions. If the branches and leaves of the green onions are relatively thin, and there are still some cases of barbed hooks, then we still need to apply the right amount of potash. In addition, each of the green onions grows with an appropriate amount of fertilizer, and supplements the nutrients needed for the growth of the green onions.
The above is about the introduction of green onion planting points, do you understand? To ensure that you plant high-yield green onions, these points management can not be ignored! Hope that Hui Nongwang Xiaobian finishing the shared content can help the majority of growers.
